How to work around Windows Phone SDK 8.0 installation failure caused by invalid digital certificate

How to work around Windows Phone SDK 8.0 installation failure caused by invalid digital certificate

  • Comments 41

UPDATE - A new Windows Phone SDK 8.0 setup package has been published that contains a fix for this issue.  The original workaround is no longer needed.

Recently, an issue came up that can cause the Windows Phone SDK 8.0 to fail to install on 64-bit versions of Windows 8 or Windows 8.1.  This issue will cause setup to fail and report an error like the following:

A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file.

Microsoft has published a knowledge base article with steps you can use to work around this issue.  You can find the knowledge base article at http://support.microsoft.com/kb/2897627.  Here is a quick summary of the steps listed there:

  1. Uninstall the partially installed Windows Phone SDK 8.0 if it currently installed on your computer.
  2. Download and install the updated setup package
    1. Web downloader - http://www.microsoft.com/en-us/download/details.aspx?id=35471
    2. ISO - http://go.microsoft.com/fwlink/?LinkID=257234

Here is the previous workaround that was published prior to the updated setup package being published:

  1. Uninstall the partially installed Windows Phone SDK 8.0 if it currently installed on your computer.
  2. Download the .msi and .cab files from the following 4 locations and save them to the same folder on your computer:

    http://go.microsoft.com/fwlink/?LinkId=257145
    http://go.microsoft.com/fwlink/?LinkId=257146

  3. Go to the folder that you saved the files to and run Win8SharedSDKTools.msi file.
  4. After installing Win8SharedSDKTools.msi, re-run Windows Phone SDK 8.0 setup and install like normal.

<update date="10/11/2013"> Added a step about uninstalling the Windows Phone SDK 8.0 first if there is a partially installed version on the computer from a previous failed install. </update>

<update date="10/17/2013"> Added information about the new setup package that contains a fix for the invalid digital certificate issue. </update>

  • Hi Madhur - Can you list the exact steps you have already tried and what error message(s) you are still seeing when you try to install the Windows Phone SDK 8.0 on your computer?

  • Worked for me but only after I followed this step in the MS article, without the uninstall it failed

    "Uninstall the partial installation of Windows Phone SDK 8.0. "

  • Hi AdamL - Thanks for the heads up.  It looks like that step was added to the knowledge base article after I wrote this blog post.  I've added that step to this blog post too.

  • Hi Iftikhar ali - What is the full error message that you're seeing in this scenario?

    Also, can you please use the tool described at blogs.msdn.com/.../6458047.aspx to collect all of your setup log files, upload the file named %temp%\vslogs.cab that this tool will create to a file server (such as http://skydrive.live.com), and then reply back here and provide a link that I can use to download your log files and take a closer look?

  • Awesome Aaron, this made my day. I hope this will be fixed in official download and also that this workaround is mentioned here support.microsoft.com/.../2897627. This has been broken pretty recently I suppose, first time I've run into this issue.

  • I also faced the same issue. I changed the system date to 5 months back and installed it. It worked!
